Turbulent space weather forced Orbital Sciences on January 8, 2014to postpone the launch of its unmanned Cygnus spacecraft on its first regular contract flight to supply the International Space Station.The Cygnus spacecraft had been set to take off at midday atop an Antares rocket carrying 2,780 pounds (1,260 kilograms) of gear including science experiments, supplies and hardware. However, a potent solar flare caused increased levels of space radiation that might have damaged the spacecraft's electronics. AFP PHOTO / NASA / Bill INGALLS /
